此项研究以乌梁素海引排水量为研究对象,对1980～2009年灌溉引黄水量、降水量、降雨补水量、流入乌梁素海水量和流出乌梁素海水量进行了趋势分析和相关分析。结果表明:引黄灌溉水量依据区域降水量调整大小;红圪卜排水站排入乌梁素海水量占总排入水量的90%左右;为维持乌梁素海生态系统需水量,流入乌梁素海水量与流出乌梁素海水量呈现显著相关性。 In this study, the discharge of Wuliangsu Sea was taken as the research object. The trend analysis and correlation analysis of water diversion from Yellow River, precipitation, rainfall and water inflow to Wulan Su Sea and outflow from Wuliangsu Sea from 1980 to 2009 were carried out. The results showed that the amount of irrigated water in the Yellow River Diversion Project was adjusted according to the amount of regional precipitation. The water discharged into Wuliangsu Sea from Hongjubu Drainage Station accounted for about 90% of the total discharge. In order to maintain the water requirement of Wuliangsuhai ecosystem, There was a significant correlation between the amount of water and Wuliangsu seawater flow.
